It is supposed to take a lot of time, as it tests all mpz functions for
correct operand overlap.
I just did "./configure" and "make" and "make check", and
noticed that the "reuse" test took around 110 seconds. All

It makes no sense that it takes 110 seconds. Your machine must be in
bad health. Perhaps it has problems with CPU temp and is downclocked?
I tested now on an Intel Atom, which is MUCH slower than a 2.1 GHz Amd
Bulldozer. I took 44s. On a high-end machine expect it to take around
